l1`ign`re9,"'tl1e mould completed, with its tip.

`The machineby whiehithis is'etibetcd, consists of ing opening, of a` length 'and diameter corresponding "ovuledfwith a narrow slit or opening, a, extending` from "onecnd thereof to the other,

`The case inwhichthe mould `is formed is mounted ti ot' the "mould and at" the` thor a crank l) b' l) r v l a 1 .l

position 'torcceivethe blank ll `through theieedingle thickness` ol the metal l Schedule referred to in these lI letters Patent and `making parte!" the same.

p, 'lhemamlrel corresponds inform to the mould, and is provided with a groove, b, of' a length equal to the. blank, from the base ofthe i tip to the mouth of themould, for the purpose. ot' receiving the edge of the blank E,so that it will bite upon and hohl it tightly,-

when the act of turning the mandrel will draw the blank through the feeding-openino'.

In order to prevent any longitudinal motion of" the mandrel B, while' forming the mould, it is provided with a groove, c, `j ust outside of therend of the receiving-ease A, int-o which an arm, F, lits, at right angles to the mandrel, so asto for'm a lock.

This arm l is pivoted to the case A, so that it may A cylinder, may bepresented at .oni-c to receive the blank, I hinge a dog, G, to the end ot' the case, so that its inner toothed end c shall always rest' upon the end ot the mandrel AB, outside ofthe locking-arm F, in such manner that the tooth e of the dog will fit into a groove, d, in the elul of the mandrel, so as to arrest it at-,apoint where the groove b, inn the mandrel, and the ieeding-opening a, in the case, .will be coincident. Forthis purpose the toothed ende, ot'

Ythe dog (i, must be sutiiciently heavy to keep it down upon the mandrel, while one side ot' the notch or groove d, withinwhich the tooth c interlocks, must be bevelled, to allow the toothed end ofthe dog to pass over fthe mandrel without interruptiug'its motion, while j `the-other side ot' the notch forms a shoulder, and,by

turning the mandrel backward, interlocks with the tooth of the dog, and thus brings the mandrel always with facility and correctnessfin the proper position to receive the blank.

4`The end ot' the locking-arlu li extends beyond the side ofthe receivinc-case A and is maintained in its locked position with `the mandrel by a self-lockingr latch, H, which allowssaid pivoted arm to bc readily thrown back from lthe n'iandrel. a

When the pivotedarm F is uulockcdil'om the mandrel B, -it is lu-a'fessary,` also, to remove the dog outv point of the mandrel, I arrange a swagingdie, C,

. C is brought up to form the tip, the projecting teeth the projecting end g of the mandrel will close the the swaging-die Cl, and force it up close against the In the manufacture of candle-moulds, as heretofore practised, the tip has been made of a separate piece of metal, formed into a cone, and then soldered to the mould, after the formation of the latter, which not only increased the expense of the mould, but cousumed much time in the manufacture of the article.

In order, therefore, to form the tipat one and the same operation with the formation ot' the mould, and from one andthe same piece of metal, I eut or stamp the tapering' end of the blank E Iwith three or more teeth f, each having the form of a cone, the bases of which are on a line with 'the base of the tip of the mould, so that when the body ofthe mould is formed by' the mandrel Il, the tip of the mould will consist of conical-shaped projections f, with intervening V- shaped spaces, which project from the case A,'and surround the conical 'point g of the mandrel B.

'lo bring these teeth together over the tapering having its centre coincident with the axis of the mandrel, iittedto slide upon ways h, projecting from the rear end of 'the case A, and provided with a socket, l, corresponding inform to the conical end y of the mandrel, but slightly larger in size, to compensate for the thicknessof the metal, so that when the swagc j' of the mould pass within the opening I of the die, and of course the forcing of the latter directly over conical teeth together, so that their edges join each other, and the intervening spaces closed up, thus forming the tip of the mould. The swaging-die (l is brought into action, to form the conical tip of the mould, by means ofa cam-lever, J, pivoted Yto the rear end of the frame, so as to act against an anti-friction roller, r, on the rear side of rear end of the receiving and thinning-case A., so as to entirely enclose the conical end g of the mandrel, in which position itis locked by means of a latchlcver, K, pivoted to the side of the frame, so that its weighted end will always be in position to pass over the handle of the cam-lever J, and latch itself therewith. Y

The swaging-die Gis forced back from the mandrel B, after the completion of the mould, by means of a spring, i, acting upon a central longitudinal rod, j, attached to Athe under side of the swaging-die C, so that it isonly necessary to lift the latch K from the handle of the cam-lever J, when both the lever aml the swaging-die are forced back, as before stated, in a position to be in readiness to form the tip of 'the next mould.

rlhe mould thus formed, it will be seen, is still locked in the groove b of the mandrel by its bent lip a.

lo release it from thc mandrel B, and to straighten it,`so that it may be withdrawn from the mandrel a perfect mould, with the edges just overlapping each other, I secure in openings formed in the side of the forming-case, so as to communicate with the interior opening therein, two or more rods, m, placed so as to strike the mould obliquely to a horizontal line, as shown in fig. 5, having their' inner ends rasped, and their outer ends united by a connecting-platea@ secured by a screw to the case, the shank of saidscrew allowing the plate L to move, with its arms fm, toward and from the mandrel B, while a spring, O, arranged between the case and the plate L, coustantly tends to force the latter outward, so that when the bent lip n. of the mould is desired to be released from its lockingsgroove b, it is only necessary to press the plate L inward, which carries thel rasped ends of the oblique arms "m directly against the side of the mould, so as to press aud bite thereon with suliicient force to prevent the mould from turning,

while, with a quick turn of the mandrel B, the said bent edge is released from its groove b, and made to conform to the curve of the mould, and thus the mould is completed. v

Instead of the means just described of straighten-- ing the bent lip n of the mould, so that it will conform to the, curve of the mould, the mandrel, with the mould thereon, may be drawn half way ont of the cylinder, so that the bent lip n may be liberated from its holding-groove on said mandrel, the mould turned partly around, and pressed back to its original place in the forming-cavity, with its edges slightly overlapped. IDue revolution given to the mandrel, andthe required cylindricalforln is imparted to the mould.

The blank E from which the mould is made, is first cut or stamped from a sheet of metal, of the required size and shape, as represented in fig. 7.

It is then placed within the opening a ofthe receiving-case A, and fitted securely in the` groove b of the mandrel B, soas to stand ina vertical position,

as shown in tig. 1, one side ofthe opening a in the case being bevelled, to facilitate its entrance therein.

The attemlant then grasps the crank D of the man;t drel, and turns it, which bends the lip a of the blank into the groove b,-so as to lock it with the cylinder; then continuing to turn the mandrel one revolution, it will 'draw the blank through the opening and around said mandrel. l The swaging-die C is then brought into action by means of the cam-lever J, to form the conical tip of the mould, closing up the conical teeth f of the blank, and another revolution is given to the mandrel, to render the joints o f the tip even. f

Ihp rasped ends of the oblique rods on. are then pressed sharply against the mould on. the mandrel,

with sufficient force to prevent it from turning while;

the mandrel is turned quickly by its crank D, so as to liberate the locking-lip nfof the mould from its groove l), thus bringing it into the proper form.

lhe swaging-cam J is released, the locking-arm Fis thrown back, the'mandrel -B withdrawn frolu the forming-case A, the mould removed, the mandrel replaced and locked within the forming-case, and the machine is in readiness for the formation of another mould. v

In this manner moulds may be made with great facility, requiring only to have the joints of the body and the tip soldered in the usual manner.

Dipper-handles, and other similar articles, may also be made with great facility, and at a great saving of expense, by this machine.

Having thus described my invention,
